LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 472,483, dated April 5, 1892.

Application filed September 9, 1891. Serial No. 405,175. (No model.)

To all whom it may concern: into the casing and resting on or supported Be it known that I, GEORGE L. LOoMIs, a from the bottom thereof, said spring exerting citizen of the United States, residing at Northa forcing action upon the end portion of the ampton,in the county of Hampshire and State hinge member c, which is between the mouth 5 of Massachusetts, have invented new and useof the casing-socket and the pivotal line con- 5 5 ful Improvements in Lock-Hinges, of which stituted bythe studs d.

The cal resort for the production of the said studs spring force is thus relieved from the hinge 5o d being imlnaterial. There is a spring f let member c, so that there is no bind between the i studs d and the hook-lugs, and on swinging the movable parts into the position shown in the full lines in Fig. 2 the said movable parts may be carried bodily forward, as shown by the dotted lines in said Fig. 2, for the detachment, as indicated.

The spring in order to be effective in maintaining the blind in its set position, resisting the wind force, is necessarily quite heavy and powerful, and much difficulty has been experienced in the detachment of the parts heretofore in the absence of the capability as now afforded by the provision of the hole in at least one of the socket-lugs for the insertion of a pin or the nail for temporarily maintaining the spring-compression, as stated. Practically the same advantage also arises by the provision set forth in the assemblement or re-engagement of the parts, and the nail or pin serves, also, while the members a and c remain detached, to prevent the spring and the bushing therefor from being forced or permitted to pass out of the casing-socket.

That I claim, and desire to secure by Letters Patent, is-

A lock-hinge consisting; of two members c and ct, the former having the lateral pivotforming projections el d and the member a comprising a soclceted casing opened at its outward end and provided with the opposing hook-formed lugs b ZJ, adapted for t-he engagement therewith'iof said projections d, the spring disposed in said casing and exerting an outward forcing action in relation to the member c, and one of the hook-formed lugs having a hole I@located as described and adapted for the passage therethrough and engagement therein of a pin or the like for temporarily maintaining the spring under compression for relieving the bind exerted by the spring between the engaging portions of the hinge members, substantially as described.
